An acronym for "graphic novel". A sort of expanded comic book but one that tells a complete story rather than a classic comic book in which the story does not have a traditional ending and may be told for years.

G.N

G.N.S - Gossip News and Scandal. Invented by a bored Civil servant Bill 'The Knowledge' Chapman working for an Incompetent Quango. GNS is spread around the organisation in an attempt to make a Miserably Stagnant job a little more bearable.
